TO ALL WHOM IT MAY concerns;

' Be it known that we, Gnonen HARSI-N and T. M. Kmnrarnrcir, oflijrlivill, iiithe county of W'apello, and State of Iowa, have invented certain new and useful Improvements in Hand-Looms; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being bad-to the annexed drawin'gs, making part of this specification, in whieh- Figure 1 is a perspective view.

Figure? is a vertical section. Figure 3 is a top view of the front part of the loom; and Figure! is'a vertical section of parts of the mechanism. The same letters are employed in the designation of the same. parts.

Our improvements relate to that class of looms in which. the power is applied by hand, and theirnature will appear from the following description and claims. I

A is the batten or lathe, by the oscillation of which the mechanism is actuated. It is connected by the rod B with the swinging arm 0, pivoted to the frame of the loom. This oscillates with the batten, andgives a reciprocating motion to the hooked rods D and E. a The rod E-has a notch'in the bottom intended to push against bars across the double wheel G, giving a quarter revolution to the wheel with each motion of thelathc towards the operator. The treadles F, pivoted to the frame at one end, rest on camsG on the 'axle of the wheel G.-

The cams are placed at right angles to one another, as shown in fig- 4,. and with each movement of the lathe towards the operator. The treadles F are alternately raised by the cams. The treadles, on the descent of the cams, are depressed by springs F. H are the harness-frames, attached by eyes in their ends to rigid guiderod s, attached to the frame in a vertical position. The harness-frames are attached to the treadles by'rods H. I'is'the yarn-roller, which has a pulley on the end, around which a cord, I, is carried,'one end 'of which is;

attached to the frame,.and ,the other to a lever, I, by drawing on which the cord can be tightenedor loosened. The rack 1 holds the lever inplace. By means of the lever the operator can regulate the tension applied to the yarn-roller. i

The cloth-roller is actuated by a take-up, as follows: A pinion, K, on the eloth-roller K, gears into another on the shaft of the ratchet-wheel-K. This ratchet-wheel is caused to revolve with the motion of the lathe, as

the cloth is woven by the feed-hand K attached to the lever Kfl which is moved backwards and forwards by the 1 connecting-rod K fastened to the'crankarm K A reciprocating motion is given to the crank-arm K by a spring, K attachedto the axle 9f the crank, and resting onpins projecting from the face of the double wheel G. As this wheelrevolves, the spring will be raised, pushing forward the feed-band, and moving the cloth roller. When the pin passes from under the spring, the latter fiies back, thus retracting the feed-hamd; the motion being so regulated by the position of the pins,'that the cloth shall be wound up at the proper time in relation to the movement of the shuttle. I

' The shuttle is thrown by the following means The wheel L attached to the shaft L, has pins projecting from its ,face, to engage the hook upon the arm .1), which is actuated by the oscillating arm C, the rods'D and- E operating their respective parts of the mechanism alternately. Arm, M, is attached to the'shaft L, having friction-wheels on their extremities, which, with the revolution of the shaft, bear successively on the arm N, which are constructed with' faces inclined in the-direction of the revolution of the arm M. These arms pro: ject from counter-shafts N, turning on journals resting on the frame. The picker-staff O are fastened to these countershafts, and when the arm N is pressed down by the arm Mstriking against it, thepicker-staif will be thrownsmartly forward, throwing the shuttle attached thereto by cords. 'The picker-staff are drawn instantly back to their original vertical position by the spring I, connected with the counter-shafts by cords P.

. The shuttle-boxes A are connected with the lathe by hing es, which. will permit themto be folded down when not in use, and are supported in a horizontal position by hooks attached to the lathe whenthe loom is in operation.

7 What we claim as our invention, and desire to secure by :Letters Patent, is'

1. The combination and arrangement of the harness-frames H, attached to guide-rods H the .treadlesF;

cams G, wheel G notched bar'E, oscillating-arm C, rod B, and lathe A, substantially as described.

2. The take-up mechanism consisting of the wheel G, and parts K K K K, K and K nrrringod siibstantially as described. 1 I

3. The combination of the reciprocating bar I), wheelL, .shaft L, arms M and N, and pickerstaff 0, substantiaily as described. 7 7

4. The arrapgement of the yarn-roller I, having apulley on its end, and the cord 1, one end being fastened to izhe frame, ahd the other to'i-he lever 1 adj'ustably held in position by the rack I for the purpose of regulating the tension of the yarn-roller, substantially as described. i

In testimony whereof, we have'signed our names to this specification-inthe presence of two subscribing witnesses.
